The membrane (M) terminates at its periphery in an anchorage beading profile (K) which locates within a matching groove (KK) forming part of the clamping profile (5). The clamping profile is located and clamped (2) within a surrounding metal profile (B).

Description

Fixing profile.

The invention relates to a fixing profile. according to the preamble of claim 1.

For example for swimming pools, patios with arcades, gas stations or facades a new technology is known, which called architectural construction with membrane. The constructions of this type in the form of roofs or facades The mounting rails are mounted on a supporting structure in a predetermined frame, in which they are anchored with their membrane edges that line the fields between the rails of fixation (WO 96/21072 A). The membranes can be of one or several layers and can be made of plastic sheets or textiles and may be tensioned or covered by brackets or cable constructions on the lower or upper side or can also be under internal pressure as called mattresses tires without or with tensioning elements. The membranes can be transparent or stamped or coated and in many cases not only they fulfill a coating function but also a function of isolation. At the edge of the membrane a weatherstrip is inserted in a bag that extends in the longitudinal direction. The edge it is threaded with the weatherstrip in a metal fixing profile in a weatherstripping channel there formed in the longitudinal direction of the weatherstripping channel Since membranes of this type may have perfectly a length of 100 m or more, the threading process It is extremely expensive and long, particularly if the membrane is prestressed by its own weight or for other reasons in the direction opposite the fixing rail, since the resistance is high to friction in the weatherstripping channel and in the exit slit. In addition, the edge of the membrane must be tensioned in the assembly, in particular from the ends of the fixing profile, to eliminate transverse folds or generate the necessary pre-tension of the membrane in the longitudinal direction of the fixing profile. Do not However, due to the frictional resistance in the channel weatherstrip and in the exit slit, in practice they can only the last meters of the edge of the membrane, since the tensile forces are compensated by frictional forces already at a relatively short distance from fixing profile ends. Therefore, during threading it must be continuously tensioned at the same time, which is a process expensive and long. Another drawback is the fixing rails expensive and expensive fixing profiles and the fact that the edge of the membrane can barely redo in a moment later without the membrane suffering damage.

For the document FR-A-2489678 an element is known of separation wall to separate different work areas in Offices. The separating wall element has a U-throat continues abroad, in which a marginal joint is knotted in the form of an elastomeric material frame. The marginal board forms a groove that leads to a weatherstripping channel through a point narrowed In the marginal joint, the edge of a width of decorative coating folded around the edge of the separation wall element.

In a roof system known for the DE 43 27471 is fixed in a groove for fixing a profile base a metal profile and hollow, which has a weatherstripping channel continuous in the longitudinal direction and an outlet slit narrowed A material is anchored in the weatherstrip channel textile or flexible foil, this edge being made as a bag of weatherstripping with inserted weatherstripping. Weatherstrip bag with weatherstrip inserted is threaded from a front side of the hollow profile in the longitudinal direction of the weatherstripping channel.

From document DE 41 05 449 A a known known weatherstrip profile of elastic material for fixing the Edge of a bellows of an articulated vehicle. On the edge of the bellows It is integrated by welding a tension cable resistant to the traction, which fixes the edge of the bellows in the weatherstrip profile and whose ends are joined by a tensioner. The weatherstrip profile is rides on a metal support profile, which keeps closed together not positive the outlet slit of the weatherstripping channel.

As in the case of constructions in In general, membrane constructions are also insured. Lately the intensity of storms or hail has increased. Although the membranes of such constructions are they consider harsh and storm resistant, the recent past has shown that extreme weather events can unexpectedly cause damage by objects dragged by the storm or by extremely large hail grains or shapes unfavorable This can condition considerable difficulties in As for insurance. Therefore, it is necessary to configure the Membrane constructions of this type are resistant to hail or storm resistant.

The invention aims to indicate a fixing profile of the type indicated at the beginning that allows the less a considerably simpler assembly of the membrane.

The stated objective is achieved according to the invention with the features of claim 1.

The abandonment of a fixing profile made of metal going to a fixing profile made of rubber or elastomer It carries multiple advantages. The main advantage is that the elasticity of the fixing profile allows at least in the area of the exit slit open the exit slit at least temporarily elastically to such an extent that the edge of the membrane with the weatherstrip can be threaded comfortably in the direction transverse with respect to the longitudinal direction of the channel of weatherstripping Since it is no longer necessary during threading perform a longitudinal movement of the membrane edge with the weatherstrip, weatherstrip channel and outlet slit can dimensioning so narrow that finally an adjustment is achieved very strong pressing with a practically ideal shutter effect for the edge of the membrane. In addition, the stretching of the membrane in the longitudinal direction of the edge to finish the assembly can be done in a much more efficient way than to date, because the fixing profile can expand along with the edge threading in the longitudinal direction or because the forces of expansion persist without problem at least a very long stretch at length of the fixing profile. Another advantage is in that the fixing profile can be mounted thanks to its material in curvatures in any direction, which improves considerably The configuration possibilities. So to speak, they can be formed of the fixing profile closed frame structures, of so that the shutter problems that existed up to the date in the angular joint areas. Fixing profile At the same time it serves as a accommodation lane, an element fixation and sealing. Since, thanks to the material, the profile fixing can also be folded or folded, the edge of membrane can be threaded for example already by the manufacturer in the fixing profile and can be transported with the membrane folded to the construction site Only thanks to the replacement profile fixation after threading, the membrane edge with the weatherstrip is held so firmly that this union no longer separates during the transport or during assembly. During assembly, a blocking element or force distribution in the profile of fixing to reinforce or stabilize the joint for later use. Since membranes of this type are made in most of cases with a size slightly smaller than just, so that they remain strained in the mounted state, threading in the fixing profile in the transverse direction with respect to the longitudinal direction of the weatherstripping channel before assembly is an immense advantage, which It reduces effort and time. Since the clamping profile has a shutter function, elements of additional shutter. Thanks to the firm edge seat with the weatherstripping in the fixing profile, however it is not necessary weld on the membrane edge a bag for the weatherstrip, but the edge should only be folded around the weatherstrip and threaded along with this one. Even in the case of multi-layer membranes inflated to form pneumatic mattresses, this may be enough and allows to give up the welding of bags. Profile mounting of fixation is carried out by suitable fixing means, such as eg clamping hooks or screws in the necessary distances from the static point of view. The blocking element or force distribution of a more rigid material serves to follow distributing the load, the same being fixed in positive union and / or not positive in the fixing profile correspondingly formed. The function of load distribution can also be assumed by the corresponding fixing means, eg by hooks with wide support ends or continuous metal profiles. The corners can be continuous rounded without joint, that is, the known shutter problem does not occur in the joint of all conventional systems with shutter to Pressure. Another advantage is that pneumatic mattresses air impermeable can be formed or fixed without welding by two different membrane materials, if these materials do not It can be joined by welding. The cross section of the profile of fixation can fulfill additional functions, such as functions of fixation / padding when placed on the supporting structure, e.g. in a vertical throat edge or when connecting adjacent seals or they can have a thermal separation function.

A membrane construction with a membrane for weather protection in the fixing profile offers substantially greater security against damage caused because of the weather that has been possible to date. By For example, the requirements can be easily met from the point view of the insurance by means of a membrane for protection Against the weather. The membrane for protection against weathering keeps the direct influence of objects away dragged by the storm or large hail grains of the the membrane itself of the construction, can provide a additional insulation effect and maintains the function of the construction even if the membrane itself is damaged bliss

fig. 8, a cross section of a part of A membrane construction.

In fig. 1 you can see a support 1 of a bearing structure not shown in detail in a construction with membrane B, which serves to anchor at least one M membrane (in the form of a plastic sheet or a textile). M membrane has at least one layer (as indicated by dashed lines interrupted can also present two layers or even three layers). The edge R of the membrane M is fixed with the help of a weatherstrip K in a weatherstrip channel KK of a fixing profile H, the edge R extending through an outlet slot S of the fixing profile H out, for example starting from a V narrowing provided in the KK weatherstrip channel. At least in the zone of the KK weatherstripping channel or the outlet slot S, the profile fixing H is preferably made entirely of rubber or G elastomer, for example of vulcanized EPDM or rubber silicone or the like and can be called flexible, that is, it is expandable in the longitudinal direction and is flexible in the transverse direction with respect to the longitudinal direction of the channel of KK weatherstripping being able to bend in practically all addresses.

The fixing profile H is fixed on the support 1 with fixing clips 3 and fixing elements 2. You can also protection provided 4.

In the embodiment shown, the profile fixing H has a main part of wall profile 5 thick, here with outer contour 6 rounded convexly and a sealing lip structure 7 to cooperate with the support 1. Adjacent to the KK weatherstripping channel, a wall clamp 8 fine extends from the main part of profile 5 and delimits the exit slit S on one side, which forms with the part main profile 5 an insertion channel for an element of force distribution 10 eg continuous, which also forms a Ultraviolet radiation protection for the profile of fixing and ending in a sealing lip 9, which is tightened in the membrane M obtaining it. On the other side of the exit slit S, this is delimited by a thick-walled support lip 13, which is eg shorter than the tightening lip 8 and which has as example a grooved bottom side 14. In the transition of the part main profile 5 to the tightening lip 8 may be formed a groove 11, in which a filler profile can be knotted shown or that facilitates the elastic widening of the slit of Check out for the reasons explained below. Also in the outlet slot S can be provided with a structuring 12, for example in the form of longitudinal nerves with combs of shutter arranged between them. The cross section of the channel of KK weatherstrip is adapted for an exact fit to the section cross section of the weather K with the edge R, to generate a function of intense shutter, as soon as the exit slit S has been closed again, as shown here. Also in the slit of output S itself a shutter function is achieved at the two sides at the edge R. The edge R can be realized by other as welded bag for threading the weatherstrip or it can be formed only by a fold without welding. With just a K weatherstrip several M membranes can be fixed at the same time.

The edge R with the strip K can be threaded with different shapes in the weatherstrip channel K of the fixing profile H. The edge R with the strip K can be threaded, for example, by the manufacturer of the M membrane and may already be fixed in the M membrane for transport and assembly. On the other hand, naturally it is also possible not to thread the edge R with the weatherstrip K until it is in the place of assembly. In any case, threading is done in the transverse direction with respect to the longitudinal direction of the KK weatherstrip channel by means of a temporary elastic widening of the outlet slit S, by example with the help of an auxiliary device that will not be explained in detail. The outlet slot S widens to such an extent that the strip K with the edge R can be threaded without problems in the transverse direction with respect to the longitudinal direction of the KK weatherstripping channel to the inside of it, before returning to Automatically close the outlet slot S thanks to the elastic replacement capacity of the fixing profile material S generating the intense shutter function. This can also be carried out at the construction site with the clips of fixing 3 with the force distribution element 10 first Place only loosely. The fixing profile H is expandable in the longitudinal direction, specifically together with the edge R and the weatherstrip K, so that the membrane can tighten without problems To make it smooth. In addition, the fixing profile H is flexible in any direction and can also be mounted on an extension that differs from a straight line, if this is necessary for reasons architectural or for other reasons. Finally, the profile of H fixation can also be formed to have corners rounded, in which a joint is not generated that interrupts the shutter function Even a closed frame of the fixing profile H, so that all membrane edges they are tensioned and sealed uniformly.

In fig. 2, the gasket K is part of a Filling profile F, which is knotted with the edge R of the membrane M folded around it in the KK weatherstrip channel widening the output slot S, specifically in the transverse direction with respect to the longitudinal direction of the KK weatherstripping channel. How alternatively, the filler profile F could also be threaded in a welded edge bag R. The fixing profile H can comprise different areas of cross sections a, b with different shore hardness and / or different rubber materials or elastomers or reinforcements A or also another filling profile P, which favors the closing effect of the outlet slit S and that inserted after threading. The M membrane can have one or several layers.

In fig. 3, two M membranes, which are made eg of materials that cannot be welded together, are anchored in the same fixing profile H, specifically by two K weatherstrips, which are fixed together in the channel KK weatherstrip and S outlet slit. R edges are bent only around the weatherstrip K or are provided with welded bags, in which the K weatherstrings are threaded.

In fig. 4, the fixing profile H is mounted on the support 1, eg a part of a U-profile, specifically with a fixing and sealing arm 15. The membrane M can have two layers or several layers. The fixing clip 3 or a continuous fixing clip profile constitutes a protection against ultraviolet radiation for the fixation profile H.

In fig. 5 shows an M membrane of three layers with a T-bag on the edge, in which the thread is threaded K. weatherstripping

In fig. 6 clearly shows that the edge R of the membrane M is only folded around the strip K, without welding, and that the edge R is anchored tightly and not removable thanks to the sealing and tightening effect of the fixing profile not shown here (indicated by arrows 16).

In fig. 7 two M membranes are anchored with an own H fixing profile, respectively, in the support 1. The two fixing profiles H have joint structures 17 for be fixed or combined in a very tight way to each other, so that The junction area is also air impermeable. Here you can remove for example the upper fixing profile H with the upper membrane, while the lower M membrane remains with its fixing profile H in the mounting position. Each profile of H fixing could increase the clamping force for the other, in particular during transport and assembly.

Fig. 8 clearly shows a part of a construction with membrane B, of which a fixing rail 18 for the edges of two membranes M is mounted on the supporting structure T. M membranes have, for example, several layers and are anchored on a regular basis with weatherstrips K in their marginal areas R in the inside the fixing rail 8. The fixing rail 18 is closed by a superior support 1, which also generates the sealing effect for the membranes M. With the elements of fixing 2 for the support 1 also clamps 3 are fixed, which fix fixing profiles H to anchor the edge of a membrane of weather protection M 'above the membrane M. Lo essential of this solution is that the membrane itself is protected by the weather protection membrane M 'additional against environmental influences such as damage caused by thunderstorms or hail, that is, the protective membrane against the weather M 'assumes here the function of a sacrificial membrane, if necessary, with an additional isolation effect. The membrane of weather protection M 'can rely directly on the upper layer of the M membrane or can form with it a interstitium in which there is overpressure.

The weather protection membrane M 'is anchored by the rubber or elastomer fixing profile H which seals with its sealing lip structure 7 in the support 7, which also seals with the support lip 13 and the lower side 14 the upper side of the upper layer of the M membrane and that anchor also the weatherstrip K and the edge of the protection membrane against M 'weathering as explained at the beginning. He thin-wall clamping lip 8 is fixed by an element of force distribution 10 in the watertight position of the slit of exit S. It is also essential that the strip K be threaded with the R edge of the weather protection membrane M 'in the transverse direction with respect to the longitudinal direction of the channel of KK weatherstrip in this one, specifically elastically widening the exit slit. The sealing lip 9 shutter on the side upper of the M 'weather protection membrane.

The fixing profile H can now be joined by the manufacturer or elsewhere to the protection membrane against the M 'weather, which facilitates assembly. As an alternative, the M 'weather protection membrane can also threading in the place of works as described in the address transverse with respect to the longitudinal direction of the channel of KK weatherstrip in this one. The weather protection membrane M 'can be a sheet or a textile, like at least one of the layers of the other M. membranes

In case the fixing profile is mounted on the frame of a retrofitting in the fixing rail 18, is The type of fixing shown in fig. 8. If instead it is planned in advance to additionally fix a membrane of weather protection M ', the fixing rail 18 can have been conceived in advance in such a way (not shown) that the fixing profile H can be fixed comfortably in another way and can tension so that the load is distributed and that it is watertight.

The fixing profile H could also get into pressure in a kind of channel that fixes the fixing profile automatically or with local locks in the mounting position, if necessary taking advantage of membrane tension. Here could a wedge shape or a dovetail structure be used.
